Kazuhisa Takemura is a Professor at Waseda University's School of Humanities and Social Sciences where he has served since 2003. He also directs the Waseda University Center for Decision Research (since 2007) and serves as Director of the Medical Safety Promotion Organization. His academic credentials include dual doctorates: a Ph.D. in System Science from Tokyo Institute of Technology (1994) and a Ph.D. in Medicine from Kitasato University (2013). Dr. Takemura's educational journey began at Doshisha University with undergraduate and graduate studies in Psychology, followed by interdisciplinary studies at Kyoto Institute of Technology. His research career shows a remarkable interdisciplinary trajectory spanning psychology, medicine, mathematics, and decision science. His research focuses on social psychology and behavioral decision theory, with specific interests in consumer behavior, risk perception, and decision-making processes. He employs diverse methodologies including eye-tracking experiments, mathematical modeling, and neuroeconomic approaches. Recent work examines multi-attribute decision strategies, consumer responses to energy labels, breast cancer screening behavior, and risk tolerance measurement across cultures. His research demonstrates consistent integration of theoretical frameworks with practical applications in consumer protection, medical decision-making, and public policy. Dr. Takemura's recent publication record shows remarkable productivity, with numerous articles in 2023-2025 across journals spanning psychology, mathematics, public health, and energy efficiency. His work reveals interdisciplinary connections between cognitive psychology, behavioral economics, and mathematical modeling of decision processes. He frequently collaborates with researchers across disciplines and countries, demonstrating global engagement in his field. Award for Science and Technology from MEXT (2024) for 'Reconstruction of Behavioral Decision Theory and Its Social Practical Research' Distinctive Achievement Award (Chikio Hayashi Award) from Behaviormetric Society (2022) Kimura Award from Transdisciplinary Federation of Science and Technology (2021) Fellow of the International Association of Applied Psychology (2018) Multiple Best Paper Awards across various academic societies Dr. Takemura serves as Editor in Chief of The Japanese Society of Theoretical Psychology journal and on editorial boards for Scientific Reports (Springer Nature) and The Japanese Society of Social Psychology. His leadership extends to directing research centers and participating in national and international research collaborations. His work bridges theoretical advancements in decision science with practical applications in consumer protection, medical decision-making, and public policy development. He leads the Waseda University Center for Decision Research, which functions as an interdisciplinary hub investigating human decision processes through psychological, economic, and mathematical perspectives. His research program demonstrates how theoretical insights about human decision-making can inform practical interventions in consumer protection, healthcare, and public policy.
